So we’re sharing anecdotes so here’s mine: the speed in weight loss matters, in the sense that faster weight loss might not be the best. Your body will try to regain weight if you don’t give it time to get accustomed to the new weight.
In late 2020 / early 2021 i did the Dukan diet and lost ~10kg in like two months and a half, i lost like a kilogram (about two pounds) per week, my body was perfect.
Then i stupidly eyed the next challenge (quitting smoking) and gained everything back (with intenterests, damnit).
I should have really focused on consolidation, that for the dukan diet means slowly reintroducing other foods slowly to let your body get used to the new state of affairs.
Last year started dieting again and i lost 10 kilograms again, over a year, by mostly eating less (i amicably call it “controlled malnourishment”). This time i’m not gaining it back and i think it’s because even in the weeks where I’ve exceeded, my body got time to get acquainted to the new weight. During this last year i hit a plateau as well… i just had to be patient.
